Answer:
2/9
Step-by-step explanation:
We have 3 video games
I will assume that pirates have a water theme, so 2 have a water theme
That leaves 1 game with no water theme
P (no water theme) = games with no water theme/ total
=1/3
The games are 6 7 and 9 dollars
2 games are at least 7 dollars
P( at least 7 dollars) = games at least 7/ total
=2/3
P ( no water theme at least 7 dollars) = P (no water theme) * P( at least 7 dollars)
= 1/3*2/3
= 2/9
B is the answer
B- prices are all higher than 20$ all other of the answer choices are lower than 20$
Answer:
i)The correct option is D.) 99.74%
ii) The correct option is B.) 68.26%
Step-by-step explanation:
i) P(10≤X≤70) = P( (10−40)/10 ≤Z≤ (70−40
)/10 ) = Pr(−3≤Z≤3)
= 0.9987 - 0.0013 = 0.99734
Therefore the percentage of Jen's monthly phone bills are between $40 and $100 is D.) 99.74%
ii)P(2.1≤X≤3.1) = P( (2.1 − 2.6) /0.5 ≤ Z ≤ (3.1−2.6
)/0.5) = Pr(−1 ≤Z ≤1)
)
= 0.8413 − 0.1587 = 0.6826
Therefore the percentage of students at college have a GPA between 2.1 a,d 3.1 is B.) 68.26%
